- Backported the MYSQL_SYSVAR_SIZE_T to 10.0
- The parameter innodb_ft_result_cache_limit was only 32 bits wide
also on 64-bit systems. Make it size_t, so that it will be 64 bits
on 64-bit systems.
- Added a test case that show how innodb_ft_result_cache_limit variables
behaves in 32bit and 64 bit system.
* define MYSQL_DYNAMIC_PLUGIN only for server plugins
* don't typedef my_bool in mysql.h if plugin.h has already done it
* fix the include guard in plugin.h
* Extract it into the "encryption_scheme" service.
* Make these engines to use the service, remove duplicate code.
* Change MY_AES_xxx error codes, to return them safely
from encryption_scheme_encrypt/decrypt without conflicting
with ENCRYPTION_SCHEME_KEY_INVALID error
instead of having it 1K everywhere, make it 1K on 32-bit and 2K on 64-bit.
As the latter has larger pointers (and larger sizeof(SHOW_VAR),
it needs a larger buffer to store the same amount of SHOW_VARs
Due to how gap locks work, two transactions could group commit together on the
master, but get lock conflicts and then deadlock due to different thread
scheduling order on slave.
For now, remove these deadlocks by running the parallel slave in READ
COMMITTED mode. And let InnoDB/XtraDB allow statement-based binlogging for the
parallel slave in READ COMMITTED.
We are also investigating a different solution long-term, which is based on
relaxing the gap locks only between the transactions running in parallel for
one slave, but not against possibly external transactions.
The merge is still missing a few hunks related to temporary tables and
InnoDB log file size. The associated code did not seem to exist in
10.0, so the merge of that needs more work. Until this is fixed, there
are a number of test failures as a result.
Add an error code to the wait_for_commit facility.
Now, when a transaction fails, it can signal the error to
any subsequent transaction that is waiting for it to commit.
The waiting transactions then receive the error code back from
wait_for_prior_commit() and can handle the error appropriately.
Also fix one race that could cause crash if @@slave_parallel_threads
were changed several times quickly in succession.
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Implement facility for the commit in one thread to wait for the commit of
another to complete first. The wait is done in a way that does not hinder
that a waiter and a waitee can group commit together with a single fsync()
in both binlog and InnoDB. The wait is done efficiently with respect to
locking.
The patch was originally made to support TaoBao parallel replication with
in-order commit; now it will be adapted to also be used for parallel
replication of group-committed transactions.
A waiter THD registers itself with a prior waitee THD. The waiter will then
complete its commit at the earliest in the same group commit of the waitee
(when using binlog). The wait can also be done explicitly by the waitee.
(it worked fine with the modern gcc, but failed on some other compilers).

USING THE PLUGIN INTERFACE.
ISSUE: No support for floating-point plugin
system variables.
SOLUTION: Allowing plugins to define and expose floating-point
system variables of type double. MYSQL_SYSVAR_DOUBLE
and MYSQL_THDVAR_DOUBLE are added.
ISSUE: Fractional part of the def, min, max values of system
variables are ignored.
SOLUTION: Adding functions that are used to store the raw
representation of a double in the raw bits of unsigned
longlong in a way that the binary representation
remains the same.
(because it's conceptually wrong. only the user can decide whether the kill is
allowed to leave tables in the inconsistent state, storage engine has no say in that)
